Device for forming lightweight paper into rolls without any core

ABSTRACT

A device for coreless rolls of very lightweight fiber material, such as tissue, comprises feeding one or move continuous webs of the tissue material into juxtaposition and then for directing it into association with a perforator and a slitter. The paper which has been slit is then fed along a feed path onto winding mandrels. The windup of the tissue on the mandrel is effected by first wetting the edge so that it engages with the mandrel. The tissue is wound into a coil of predetermined thickness and it is broken away from the continuous web along the perforations by the simple expedient of moving a flat boardlike member upwardly through the path of movement of the tissue to sever it along the perforations. The end is guided along the roll by a semi-annular member which engages around the exterior surface of the tissue roll. Thereafter, the mandrel is released at one end and pivoted outwardly from its support and the wound tissue roll is pulled off an end thereof. It is also possible with an embodiment of the invention to feed the tissue which has been slit into guide tubes or folding gauges which fold them into one or more folds as they are wound into a coreless roll.

. ATTORNEY DEVICE FOR FORMING LIGHTWEIGHT PAPER INTO ROLLS WITHOUT ANYCORE BACKGROUND OF THE INVENTION 1. Field of the Invention Thisinvention relates in general to the construction of devices for rollingpaper material into small size rolls and, in particular, to a new anduseful device for effecting the rolling of a lightweight paper such as atissue into coreless rolls of predetermined length and thickness.

2. Description of the Prior Art At the present time, there are knowndevices for slitting paper along longitudinal cutting lines to form thepaper into individual roll lengths and for rolling these rolls ontocores. The core which is employed is usually a fiberboard material whichdoes not interfere with the use of the tissue. For many present dayapplications, it is desirable that the tissue be wound without anyfiberboard core and that the winding device provide means for easilyseparating the tissue into individual roll lengths and preferably forforming more than one roll length at a time. I

SUMMARY OF THE INVENTION In accordance with the present invention; thereis provided a device which is capable of feeding very lightweight tissueinto association with means for perforating it and for slitting it intoindividual lengths and for rolling each length into a coreless roll ofpredetermined lengths. A feature of the construction is that theindividual lengths are fed, after slitting, into association with amandrel where they are engaged with the mandrel by wetting the end ofthe tissue to cause it to adhere to the mandreLThe tissue is severedfrom the remaining length of tissue web after winding by moving a flatboard upwardly through the path of movement of the tissue to sever italong a perforation line. It is to be understood that one continuous webof material may be utilized. However, in the following description,several thicknesses of tissue are fed to the perforator and slitter andthey are separated after the slitting operation is carried out in orderthat there be a sufficient body of tissue paper presented for theslitting and perforation operation-when it is done. The rolls of paper,which are wound on mandrels, and are held to the mandrels by the wettingaction, are removed from the mandrels after rolling by freeing the endof the mandrels and directing the tissue off the mandrels end after thisend has been pivoted away from its support or cradle.

In accordance with another embodiment of the invention, thepaper'isdirected after slitting into individual folding gauges which effect thefolding of the paper as it is fed into one or more folds prior to itbeing fed onto the winding mandrel.

Accordingly, it is an object of the invention to provide a device forforming coils of lightweight paper, such as tissue, individual sheetsand for perforating the sheet and for thereafter winding the perforatedsheet on a mandrel, separating the individual rolls which are wound fromthe remaining sheets along the perforations, and then removing thesheets from the mandrel.

A further object of the invention is to provide a device for windingvery lightweight paper which includes feeding one or more thicknesses ofthe paper into juxtaposition and then perforating and slitting thesheets together, subsequently folding them by passing them throughfolding guides and thereafter winding them without a core'directly on amandrel from which they are remove.

A further object of the invention is to provide a winding mechanismwhich is simple in design, rugged in construction, and economical tomanufacture.

The various features of novelty which characterize the invention arepointed out with particularity in the claims annexed-to and forming apart of this disclosure.

GENERAL DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to thedrawings in particular, the invention as embodied therein and shown inFIGS. 1 through 12,

comprises a device for perforating, slitting and then In accordance withthe invention, as shown in FIG. 3, preferably two lightweight paper websor sheets and 12 are fed over dancer rolls 14 and 16 and combined onto afeed roll 18. One of the tissues is also guided by a guide roll 20. Thecombined webs 10 and 12 move between the nip of the roller 18 and acounterroller 22 into association with perfrorating means, generallydesignated 24.

The perforating means 24 includes a rotatable perforator block 26 and aresilient counter-roller 28 which receives the perforating bladeprojections 32 of a perforating blade 34. (See FIG. 6). The blade 34includes projections 32 spaced along the length of the blade andseparated by recesses 36 which are located at the areas in which thetissue is not penetrated. The blade 34 is carried in a recess 38 of therotatable block 26 and it is held in an adjusted position by a set screw40, as shown in FIG. 6.

After the webs 10 and 12 in their combined form, as generally designated42, are passed through the perforator means 24, they are advanced intoassociation with conventional slitter means 44.

After the passage of the combined webs 42 through the slitter means 44,they are moved to feed rolls, generally designated 58, and which includea top roller 57 and a lower roller 59 between which the combined websare fed and separated into individual webs at 12' and 10'. Theindividual webs 10' and 12 have each been slit longitudinally andperforated transversely and each is wound upon an associated mandrel 60and 62,

one pivotal universal switch bearing or joint 100 arranged atone end,after first lifting the opposite end off of a cradle 102, as shown inFIG. 11. All of the wound rolls 72 are removed at once from the mandrel60 in a direction of the arrow 104, as shown in FIG. 11. Afterwards, theindividual roll lengths 72 are separated by breaking them along the slitlines 70.

The drive for the operating mechanism shown in FIGS. land 2 and the maindrive is from a drive motor (not shown) driving through a belt 106 to asprocket 108 affixed to a shaft having a drive pinion 110. The

' drive pinion 110 is in meshing engagement with a large respectively,to form rolls 64 and 66. The rolls 64 and 66 are separated from theremaining portions of the webs 10.and 12 along the perforated lines.

The web winding operation begins, as shown in FIG. 7, in respect to theweb 10', which has beenslit along a plurality of longitudinal slit lines70 in order to define individual roll widths 72 (FIGS. 7 and 8) whichwill be separated'after they are removed from the associated mandrel 60.Initially, the leading edge of the web 10 is adhered to the mandrel 60in any conventional way. When a predetermined thickness oftissue'material has been wound upon the mandrel 60, the winding iscontinued until the perforation line 78 aligns over a breakboard 80which is part of the web separating means 68. The breaking of the tissueaway from the remaining web 10 is effected by an operation in which thesurface of the wound roll 72 is engaged by a half cylindrical shell orguide plate 84 and then by moving the breakboard 68 upwardly in adirection of the arrow 86 shown in FIG, 3.

The break of the tissue occurs along the perforation line 78, as shownin FIG. 9, and the broken end of the roll is smoothened over the surfaceof the roll by the guide plate 84. The break-board 80 is supported belowthe web feeding to the associated mandrel 60 or 62 on an upright member90 which is hinged to the board by a hinge 92. The upright member may beoriented to engage the ground or some fixed support 94 when thebreak-board 80 is lowered back into an operating position, as shown inFIG. 3. The upper end of the breakboard is hinged to a fixed member 96which carries a connecting hinge which is secured to the board. Thehinge 98 permits upward pivotal movement of the break-board 80 asdesired.

After the end of the roll has been severed from the remaining web, anddeflected around the surface of the wound roll 72, the mandrel 60 ispivoted outwardly on gear 112 carried on a shaft 114 which carries adrive gear 116. The drive gear 116 drives a gear 118 which is affixed tothe shaft 54 of the mandrel roller. This shaft 54 carries a sprocket 120which drives a gear 122 through a chain 124 carrying a'shaft 126 of thelower separating roller 59 which is located below the feed roll 128. Thegear 118 also drives a gear 130 to rotate the slitter shaft 52.

The gear 116 also drives a gear chain of gears 132, 134, 136 and 138.The gears 136 and 138 are on shafts 140 and 142 of the counter-roller 28and the perforator block 26, respectively.

The gear 138 also drives a chain of gears 144,146 and 148. The gears 146and 148 are on shafts 150 and 152 which carry rollers 22 and 18,respectively. Shafts 154 and 156 carry the dancer rollers 14 and 16,respectively, as shown in FlG.'2. I

The rewind drive is taken from the large gear. 112

driving gear 158 which is on a shaft which carries a' sprocket 160 whichdrives a chain 162 to drive gears 164 and 166 which are located on therewind shafts 168 and 170 for the mandrels 60 and 62, respectively. Atensioning sprocket 172 is engaged with the chain 162.

In FIGS. 13 to 15, there is shown another embodiment of the invention inwhich a web, generally desig- I nated 10", is separated into individualwidths by slitter rollers 174 and the widths are directed intoassociation with folding means, generally designated 176, whichcomprises a folding gauge or tubular member 178 through which the end ofthe sheet is initially guided by hand and out of which the sheet arrivesas a folded individual sheet 180which' is directed over a mandrel 182.The tubular fold members 178 have an initial crosssection as indicatedin FIG. 15 which gradually reduces from one end to the other togradually carry out the complete folding operation so that there is adouble folded layer which arrives at the mandrel 182.

FIGS. 16 and 17 show alternate embodiments of guide tube 178 and 178" toeffect a simple V-type fold as shown in FIG. 16 and a double foldasshown in FIG. 17.

While specific embodiments of the invention have been shown anddescribed in detail to illustrate the application of the principlesofthe invention, it will be understood that the invention may be embodiedotherwise without departing from such principles.
